Has_many :through

Hi all,

I’ve been stuck trying to get a has_many :through relationship working
on
my Rails application.

I have a Employee model, a Timesheet model and a Payment model.
The Employee has many Timesheets and a Timesheet has many Employees.
The Timesheet table will contain its ID and a Date. the Payment model is
the join table, it belongs to a Employee and a Timesheet, it also has an
extra field called hours_worked.

See below models

class Timesheet < ActiveRecord::Base
belongs_to :user
has_many :payments
has_many :employees, :through => :paymentsend
class Employee < ActiveRecord::Base
belongs_to :user
has_many :payments
has_many :timesheets, :through => :payments end
class Payment < ActiveRecord::Base
belongs_to :employee
belongs_to :timesheetend

I want to create a form where I can create a new Timesheet by chosing a
date, listing all Employees and allowing me to enter the hours_worked
for each employee.

Once I submit the form, it should create a new Timesheet, and create a
Payment for each employee with each employee’s hours_worked for that
specific Timesheet.

I hope this makes sense and I can get your help!!

Thanks

So what is not working, or which bit don’t you know how to do?

Have you worked right through a good tutorial such as railstutorial.org?

Hi Colin,

What I don’t know how to do is the nested form, and the new and created
methods in the controller for this specific association.
I have tried the relationship on the rails console and it works fine.

I actually have done the rails tutorial and had a good look through
stackoverflow, but i still can’t get my head around this one.

Appreciate your help!

My idea is to create a form along those lines:

<%= form_for(@timesheet, :html => {:multipart => true}) do |f| %>

<%= f.label “Date for timesheet” %>
<%= f.text_field :date %>

<!-- Add worked hours for each employee -->
<% @employee.each do |t| %>
      <%= f.label t.fname  %>
      <br />
      <%= f.label "Basic Hours" %>
      <%= f.text_field :basic_hours  %>
      <%= f.label "Sunday/BH Hours" %>
      <%= f.text_field :sunday_bh_hours  %>
      <br />
<% end %>

<%= f.submit 'Submit', :class => 'btn btn-primary' %>

<% end %>

Are you sure you don’t mean a Timesheet has one Employee?

Do you mean by having a Timesheet that has a employee id, the date and
the
hours worked?

My intention is to create a form along those lines:

<%= form_for(@timesheet, :html => {:multipart => true}) do |f| %>

<!--creates a new timesheet -->
<%= f.label "Enter date for timesheet" %>
<%= f.text_field :date %>

<%= fields_for :payment do |p| %>
<!-- Add worked hours for each employee -> @employee = Employee.all 

on controller (new method)–>
<% @employee.each do |t| %>
<%= t.fname %>


<%= f.label “Basic Hours” %>
<%= p.text_field :hours %>


<% end %>

<%= f.submit 'Submit', :class => 'btn btn-primary' %>

<% end %>

My issue is I can’t find a way to get this form to create the timesheet
and
the payment for each employee.

Hopes this makes it a bit easier to understand.

Thanks

Thanks for that Dave! Sometimes we over complicate stuff when learning
:slight_smile:

I just need to look into creating a form that will allow me to select a
date for the timesheet, and then loop through all employees on the
database
to give me a option to create a timesheet for each employee using that
specific date, all in one form.
The form will also allow me to enter the hours worked for each employee.
When I submit the form, it should create a timesheet for each employee
with
their worked hours for that specific date.

a little help with the form and new/create methods would be a great
help!

Thanks again…

Yes, that’s how timesheets usually work in the real world. You may be
trying to do something different in your app, if you think it will
make the program better. I’m just trying to clarify…
